The battery replacement station inquiry system of an electric vehicle disclosed by the present invention includes: an electric vehicle 10, a server 20 and an electronic device 30. The electric vehicle 10 further includes: a vehicle processor 11 and a vehicle storage device 12; the server 20 further includes : Servo processor 21 and servo storage device 22; Electronic device 30 further includes: device processor 31 and device storage device 32.

At least one battery is installed in the electric vehicle 10, the battery is used to drive the electric vehicle 10, the vehicle processor 11 of the electric vehicle 10 is used to execute various vehicle commands, and the vehicle storage device 12 of the electric vehicle 10 is used to store multiple Vehicle instructions, storing electric vehicle owner information 41 (step 101), the vehicle instructions are loaded and executed by the vehicle processor 11:

The electric vehicle 10 detects the total residual capacity 42 of the battery used by the electric vehicle 10 (step 102). Specifically, assuming that the electric vehicle 10 uses only one battery, the electric vehicle 10 detects that the total residual capacity 42 of the battery is a single battery Assuming that the electric vehicle 10 uses multiple batteries, the electric vehicle 10 detects that the total residual electricity 42 of the battery is the sum of the residual electricity of each battery.

The electric vehicle 10 will obtain the geographic location information 43 of the electric vehicle 10 when the total residual power 42 is less than or equal to the battery replacement value (step 103).

After obtaining the geographic location information of the electric vehicle 10, the electric vehicle 10 will establish a connection with the server 20 through a wireless transmission method. The aforementioned wireless transmission methods are, for example, Wi-Fi, mobile communication network, etc., which are only examples here. Therefore, without limiting the scope of application of the present invention, after the electric vehicle 10 establishes a connection with the server 20 through the wireless transmission method, the electric vehicle 10 can connect the electric vehicle owner information 41, the total residual power 42 and the geographic location The message 43 is transmitted to the server 20 (step 104).

The servo processor 21 of the server 20 is used to execute each servo command; and the servo storage device 22 of the server 20 is used to store multiple servo commands, correspondingly storing electric vehicle owner information and owner contact information (step 105) , The servo command is loaded and executed by the servo processor:

After the server 20 receives the electric vehicle owner information 41, the total residual power 42 and the geographic location information 43 from the electric vehicle 10 (step 106), the server 20 calculates the first range distance based on the total residual power (step 107) .

Specifically, in the servo storage device 22 of the server 20, the correspondence between the power value and the driving distance is pre-stored. Assuming that the driving distance corresponding to 1% power is 1 km, when the total residual power is 20%, the server 20 Half of the total residual power is 20%. The calculated reference value is 10% power. The first range distance calculated by the server 20 is 10 kilometers (that is, 1 times 10); or the driving distance corresponding to 1% power is assumed. It is 500 meters. When the total residual power is 20%, the server 20 uses the quarter of the total residual power as 20% to calculate the reference value of 5%. The first range distance calculated by the server 20 is 2.5 kilometers (that is, 0.5 times 5) is only an example here, and does not limit the scope of application of the present invention.

After the server 20 calculates the first range distance based on the total residual power, the server 20 further generates a query range based on the first range distance and the geographic location information 43 (step 108). Specifically, assuming that the query range is a rectangular range, The server 20 calculates the global positioning coordinates of the four vertices of the rectangular range based on the geographic location information 43 and the first range distance. The calculated rectangular range of the four vertices of the global positioning coordinates is the query range; assuming the query range is For the circular range, the server 20 will use the geographic location information 43 as the center of the circle. The first range distance is the circular range of the global positioning coordinates formed by the radius is the query range. The foregoing query range includes geometric shapes and custom shapes. This is only an example, and does not limit the application scope of the present invention.

After the server 20 generates the query range with the first range distance and the geographic location information 43, the server 20 can query at least one battery replacement station information 44 in the query range (step 109). The foregoing battery replacement station information 44 includes There are names, position coordinates, etc., which are only examples here, and do not limit the scope of application of the present invention.

If the position coordinate in the battery replacement station information 44 is not located on the sideline or inside of the query range, the battery replacement station information 44 will not be queried by the server 20 .

It is worth noting that if the server 20 cannot find at least one battery replacement station information 44 from the query range, the server 20 will further calculate the second range distance based on the total residual power, where the second range distance is greater than the first Range distance.

Specifically, in the servo storage device 22 of the server 20, the correspondence between the power value and the driving distance is pre-stored. Assuming that the driving distance corresponding to 1% power is 1 km, when the total residual power is 20%, the server 20 Three-quarters of the total residual power is 20%. The calculation base value is 15% power. The second range distance calculated by the server 20 is 15 kilometers (that is, 1 times 15); or it is assumed that 1% power corresponds to The driving distance is 500 meters. When the total residual power is 20%, the server 20 uses half of the total residual power as 20% to calculate the reference value of 10%. The second range distance calculated by the server 20 is 5 kilometers (that is, 0.5 times 10) is for illustration only and does not limit the scope of application of the present invention.

After the server 20 calculates the second range distance based on the total residual power, the server 20 will further replace the first range distance with the second range distance and generate a query range in conjunction with the geographic location information 43. Specifically, assume that the query range is rectangular Range, the server 20 calculates the global positioning coordinates of the four vertices of the rectangular range based on the geographic location information 43 and the distance of the second range. The calculated rectangular range of the global vertices of the four vertices is the query range; suppose the query The range is a circular range. The server 20 will use the geographic location information 43 as the center of the circle. The second range distance is the circular range of the global positioning coordinates formed by the radius is the query range. The foregoing query range includes geometric shapes and custom The shape here is only for illustration, and does not limit the application scope of the present invention.

When the server 20 replaces the first range distance with the second range distance and generates the query range in conjunction with the geographic location information 43, the server 20 can query at least one battery replacement station information 44 in the query range, specifically, if the battery is replaced When the position coordinates in the station information 44 are located on the borderline or inside of the query range, the battery replacement station information 44 will be queried by the server 20. If the position coordinates in the battery replacement station information 44 are not located on the borderline or inside the query range At this time, the battery replacement station information 44 will not be queried by the server 20.

It is worth noting that if the server 20 cannot find at least one battery replacement station information 44 from the inquiry range, it will again perform the aforementioned second range distance calculation, query range generation, and at least one battery replacement station information Query 44 until at least one battery replacement station information 44 is queried.

After at least one battery replacement station information 44 is queried by the server 20, the server 20 will then query the owner's contact information according to the electric vehicle owner's information (step 110). The aforementioned owner's contact information includes: the owner's name , Owner's phone, owner's device identification code... etc., the aforementioned owner's device identification code is for example: media access control address (MAC address), international mobile equipment identification code (IMEI)... etc., here are just examples Therefore, this does not limit the application scope of the present invention.

After the server 20 finds out the owner's contact information according to the electric vehicle owner's information 41, the server 20 can establish a connection with the corresponding electronic device 30 through a wired transmission method or a wireless transmission method according to the owner's contact information. The electronic device 30 is, for example, a computer, a notebook computer, a smart phone, etc., the aforementioned wired transmission method is, for example, a cable network, an optical fiber network, etc., and the aforementioned wireless transmission method is, for example, Wi-Fi, a mobile communication network... Etc., which are only examples here, and do not limit the scope of application of the present invention, so that the server 20 transmits the battery replacement station information 44 to the corresponding electronic device 30 (step 111).

The device processor 31 of the electronic device 30 is used to execute each device instruction; and the device storage device 32 of the electronic device 30 is used to store multiple device instructions, which are loaded and executed by the device processor 31:

After receiving the battery replacement station information 44 from the server 20 (step 112), the electronic device 30 can display the battery replacement station information 44 on the electronic map according to the battery replacement station information 44 (step 113), thereby providing the owner with A nearby battery exchange station enables the battery of the electric vehicle 10 to be replaced.

It is worth noting that the server 20 can also send the geographic location information 43 to the corresponding electronic device 30. After receiving the geographic location information 43 from the server 20, the electronic device 30 can display the geographic location on the electronic map according to the geographic location information 43 The location information 43, when the electric vehicle 10 is stolen, can obtain the geographic location of the electric vehicle 10 through the geographic location information 43 displayed on the electronic map, thereby providing the purpose of anti-theft and recovery of the electric vehicle 10.

When the server 20 queries at least one battery replacement station information 44, the server 20 may further calculate the driving distance from the geographic location information 43 to each battery replacement station information 44.

Specifically, assuming that the geographic location information 43 and the battery replacement station information 44 are in the same driving direction, the shortest route from the geographic location information 43 to the battery replacement station information 44 is found according to the shortest path route planning technology, and the shortest route is calculated The total path distance is the driving distance between the geographic location information 43 and the battery replacement station information 44; or if the geographic location information 43 and the battery replacement station information 44 are located in different driving directions, you need to find the battery replacement station information 44 nearby And then calculate the shortest path from the geographic location information 43 to the battery replacement station information 44 using the shortest path route planning technology to find the shortest route from the geographic location information 43 to the battery replacement station information 44 The total path distance of the shortest path is the distance traveled from the geographic location information 43 to the battery replacement station information 44. This is only an example and does not limit the scope of application of the present invention.

After the server 20 calculates the driving distance from the geographic location information 43 to each battery replacement station information 44, the server 20 can further calculate the power consumption of each driving distance. The corresponding relationship between the power value and the driving distance in a range distance or a second range distance can be calculated, and will not be repeated here.

After the server 20 calculates the power consumption of each driving distance, the server 20 can select the battery replacement station information 44 corresponding to the minimum power consumption, and the server 20 can transmit the selected battery replacement station information 44 to The corresponding electronic device 30 provides the battery replacement station information 44 with the shortest path and the least power consumption to the owner so that the battery of the electric vehicle 10 can be replaced.

When the electric vehicle 10 has a total residual power 42 less than or equal to the battery replacement value, the electric vehicle 10 further detects the battery voltage 45 and current 46. After the electric vehicle 10 detects the battery voltage 45 and current 46, the electric vehicle 10 can The battery voltage 45 and current 46 are transmitted to the server 20.

After the server 20 receives the battery voltage 45 and current 46 from the electric vehicle 10, the server 20 can query the clock adjustment parameter 47 of the vehicle processor 11 according to the total residual power 42, the voltage 45 and the current 46, specifically In the servo storage device 22 of the server 20, the total residual power 42, the voltage 45, the current 46, and the clock adjustment parameters 47 are stored in advance, and the server 20 can use the total residual power 42, the voltage 45, and the current 46 To find out the corresponding clock adjustment parameter 47.

After the server 20 queries the clock adjustment parameter 47 of the vehicle processor 11 according to the total residual power 42, the voltage 45 and the current 46, the server 20 can transmit the clock adjustment parameter 47 to the electric vehicle 10. After the server 20 receives the clock adjustment parameter 47, the vehicle processor 11 of the electric vehicle 10 can adjust the working clock of the vehicle processor 11 according to the clock adjustment parameter 47 to save battery power consumption.

In summary, it can be seen that the difference between the present invention and the prior art is that the server receives electric vehicle owner information, total residual power and geographic location information from the electric vehicle, calculates the first range distance based on the total residual power, and based on the first The range distance and geographic location information generate a query range, and the battery replacement station information is queried in the query range to provide the battery replacement station information to the electronic device and displayed on the electronic map.
